Forward error correction adjustments for C-V2X communications

ABSTRACT

A user equipment (e.g., C-V2X user equipment) can receive a transmission from a network device of a mobile network and decode the transmission using a first forward error correction code. It can determine an attribute of the transmission to determine a condition of the communication channel. Based on the condition of the communication channel, it can facilitate transmitting feedback to the network device, wherein the feedback is forwarded through the mobile network to an application server device that selects a second forward error correction code based on the feedback. The second forward error correction code can be transmitted to, and received by, the user equipment. The user equipment can use the second forward error correction code to decode subsequent transmissions.

TECHNICAL FIELD

The present application relates generally to the field of wirelesscommunication and, more specifically, to the selection of a forwarderror correction code in cellular vehicle-to-everything (C-V2X)communications.

BACKGROUND

Cellular communications technology, including radio access technology,has grown rapidly and evolved since the launch of analog cellularsystems in the 1980s, starting from the First Generation (1G) in 1980s,Second Generation (2G) in 1990s, Third Generation (3G) in 2000s, andFourth Generation (4G) in 2010s (including Long Term Evolution (LTE) andvariants of LTE). Additionally, fifth generation (5G) access networks,which can also be referred to as New Radio (NR) access networks, arecurrently being developed and expected to fulfill the demand forexponentially increasing data traffic, and to handle a very wide rangeof use cases and requirements, including among others, mobile broadband(MBB) services, enhanced mobile broadband (eMBB) services, and machinetype communications (e.g., involving Internet of Things (IOT) devices).

As part of the expansion of the cellular platform for new services, andto keep track with the increasing needs of the automotive industry,functionality of the cellular infrastructure is being developed toprovide enhancements specifically for “vehicle-to-everything” (V2X)communications, which can comprise, for example, vehicle-to-vehicle(V2V), vehicle-to-infrastructure (V2I), vehicle-to-network, (V2N) andvehicle-to-pedestrian (V2P) communications. This development of thecellular infrastructure, functionality, and protocols (e.g., standards)for V2X communications is often referred to as cellular V2X (or C-V2X)communications. Vehicle-to-everything (V2X) communication leveragingcellular network infrastructure can provide reliable, actionableinformation flows with high definition quality services while paving theway for connected and autonomous driving into the near future. Thecollaboration between automotive and wireless telecommunicationstechnologies is driving the next generation of autonomous vehiculardesigns. With the initial C-V2X standards developed in 2017, the LTEplatform provides a means to offer new services to the automotiveindustry. LTE and 5G evolution will continue to further drive the C-V2Xstandardization efforts to meet the increasing needs of the automotivesector with new use cases that can significantly enhance the monitoringand tracking of driver behaviors, and enhance the efficiency as well assafety of intelligent transportation systems. The development andcommercialization of C-V2X technology involves multiple stake holders,including carriers, technology providers, automobile original equipmentmanufacturers (OEMs), and infrastructure vendors, to name somestakeholders, all working together to implement and showcase thebenefits and efficiency in the use of this technology for advancedvehicular connectivity and intelligent communications.

Due to its legacy capabilities and a clear roadmap with technologyevolution, the 5G automotive association has advocated the use ofcellular technologies to redefine and enhance the transportationservices connectivity model globally. The first associated standards ofC-V2X were introduced in the 3rd Generation Partnership Project (3GPP)standards Release 14. C-V2X technology is expected to drive theevolution of mobility networks and communications that can enableadvanced use cases such as autonomous driving, traffic flowoptimization, improved safety etc., thus playing a transformative rolein connected transportation communications services. LTE-based cellulartechnologies have enormous potential to drive innovative connectivityservices in automotive sector. LTE broadcast enhancements can facilitatevehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V) andvehicle-to-network (V2N) communications, leveraging traditional cellularnetworks. While standards-based C-V2X supports a variety of operationalmodes such as vehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V)and vehicle-to-network (V2N) communications, such systems and resultingIP multicast/broadcast/unicast services need to be carefully architectedto be able to utilize the mobility network infrastructure resourcescost-effectively while driving maximum return on investment foroperators. These services need to work concurrently with the legacymobility services to meet the high-performance demands associated withthe automotive use cases, as well as have the capability to meet thescale and needs of future use cases leveraging technologicaladvancements. V2I and V2N communications can greatly facilitate smartcities connectivity and control initiatives (ex: traffic, parking,metering updates, cancellations).

The above-described background relating to wireless networks is merelyintended to provide a contextual overview of some current issues and isnot intended to be exhaustive. Other contextual information may becomefurther apparent upon review of the following detailed description.

DETAILED DESCRIPTION

The subject application is now described with reference to the drawings,wherein like reference numerals are used to refer to like elementsthroughout. The following description and the annexed drawings set forthin detail certain illustrative aspects of the subject matter. However,these aspects are indicative of but a few of the various ways in whichthe principles of the subject matter can be employed. Other aspects,advantages, and novel features of the disclosed subject matter willbecome apparent from the following detailed description when consideredin conjunction with the provided drawings. In the following description,for purposes of explanation, numerous specific details are set forth inorder to provide a more thorough understanding of the subjectapplication. It may be evident, however, that the subject applicationcan be practiced without these specific details. In other instances,structures and devices are shown in block diagram form to facilitatedescribing example embodiments.

The methods and operations (e.g., processes and logic flows) describedin this specification can be performed by devices (e.g., networkmanagement device, gateway device, etc.) comprising programmableprocessors that execute machine executable instructions (e.g., computerprogram product, computer-readable instructions, software, softwareprograms, software applications, software modules, etc.) to facilitateperformance of the operations described herein. Examples of such devicescan be devices comprising circuitry and components as described in FIG.10.

The cellular industry is striving to develop cellular V2X (C-V2X)technology and is seeking to evolve the cellular carrier's mobilitynetwork infrastructure to support advanced software features related toevolved multimedia broadcast multicast services (eMBMS) and nextgeneration new radio technologies to transport efficient unicast as wellas multicast user data in switched modes.

The present application relates to the improvement of vehicularconnectivity and integrated communications delivery model with a varietyof mobile device platforms that can be embedded in the next-generationautomotive vehicles.

While standards-based C-V2X supports a variety of operational modes suchas vehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V) andvehicle-to-network (V2N) communications, such systems and resulting IPmulticast/broadcast/unicast services need to be carefully architected tobe able to utilize the mobility network infrastructure resourcescost-effectively while driving maximum return on investment foroperators. These services need to work concurrently with the legacymobility services to meet the high-performance demands associated withthe automotive use cases as well as have the capability to meet thescale and needs of future use cases leveraging technologicaladvancements.

The increasing demand of connected cars with embedded multi-mode mobiledevice platforms to obtain rich communications and navigationcapabilities via advanced cellular technologies such as LTE and 5G leadsto significant challenges. Connected cars and autonomous driving usecases in smart cities might require high definition graphics intensivemap images in real time broadcasted to them with minimal latency andhigh quality to be able to maneuver accurately enhancing the roadsafety. In addition, high valued services such as live-streaming, smartparking and important map updates via file downloads should be deliveredwith high customer satisfaction.

In a traditional broadcast service delivery, devices tuned to receivingbroadcasts in a given Multicast Broadcast Single Frequency Network(MBSFN) serving area are often limited in terms of their service qualityduring mobility based on the dynamics of the correction patternsemployed by the LTE modems at the various signal processing layers.While messages can be broadcasted from a plurality of V2X applicationservers to several automotive vehicles simultaneously in the downstream,the unicast uplink transfers from such vehicles are not impacted. Due tothe complex dynamics of the radio conditions, multicasting in apoint-to-multipoint environment with bandwidth-limited networks becomesextremely challenging. Specifically, due to the mobility patternsassociated with these automotive device platforms when receivingmulticast user data across the eMBMS broadcast serving areas, and theircorresponding radio environments by virtue of their spectrumallocations, static methods for forward error correction (FEC) in agiven broadcast serving area will not suffice in the mobile datatransport delivery.

In a typical FEC scheme, redundant packets are generated by an FECencoder and transmitted along with source packets. As an example, on thetransmitter side, a bit string 01 can be encoded into a longer bitstring, say 00111. Once the receiver receives the encoded bit string, ituses a decoder to decode the string (00111) into the original source bitstring 01. If one of the bits was transmitted in error (e.g., 00111 wastransmitted, but resulted in a reception of 00011), the receiver sidecan still deduce that the source bit string is 01, because the corruptedstring 00011 is still more similar to the encoded codeword for 01, whichis 00111, than it is to other codewords, such as 00000 or 11110. An evenlonger codeword, say with eight characters instead of five (e.g.,01100110), while resulting in more bits being transmitted, provides formore bits to enable a detection of an error. Compared with the automaticrepeat request (ARQ), which retransmits lost data using anacknowledgement process, FEC is usually preferred for real-time videoapplications due to lower end-to-end delay.

However, FEC methods at the physical layer and/or application layersthat have been applied for point-to-point links will not work uniformlyfor live streaming and file downloads in a multicast transport scenario.With the static FEC methods, wherein the FEC rate in a given region hasbeen pre-determined at the head-end based on certain network designassumptions, the end user broadcast data services quality could beimpacted with mobility between serving areas. In a traffic congestedcell, the situation becomes worse with mobility when there is no meansto adapt the network functions via suitable interactions between radioaccess and core network nodes. These static FEC methods do not provide ameans for operators to achieve the best return on investment for theirscarce spectrum and overall network resources investments.

To alleviate such limitations associated with static mapping of FEC in ageo-fenced serving area pre-provisioned at the broadcast core networkhead-end, and to provide enhanced end user C-V2X service levelexperience in connected smart-cars and drive widespread adoption ofC-V2X with the next generation mobility technologies, the presentapplication relates to a software application intelligence layer (e.g.,an intelligent software agent based cross-layer monitoring mechanism) inplace within the embedded device platforms (e.g., middleware) in theautomotive vehicles (connected cars). This approach can be seen assimple, flexible and adaptable in real-time based on the mobilitynetwork dynamics, closed-loop radio network monitoring, and tightcontrol, as well as take into account geo-targeted broadcast/unicastapplication/services requirements.

In example embodiments, a network device executing the intelligentsoftware agent can closely monitor the northbound and southboundmessaging interactions that take place between the applications andunderlying signal processing layers associated with the mobilitytechnology, as well as the resources allocated in a targeted region.With integrated analytics capability, the network device can be operablefor monitoring, correlating cross-layer interactions, trending thedynamics of the radio channel conditions per spectral allocation for thetransported multicast user data. Such an agent can self-triggerautomated notification alerts to request enhancements from the mobilitycore network on-demand to aid in the adaptations of the FEC (e.g.,facilitate the selection of a more suitable codeword if conditions callfor it), based on the cell efficiency metrics as well as the eMBMSserving area dynamics surrounding the specific automotive vehicle'smobility path.

Further, the example integrated agent in the device middleware canperiodically track such performance at the individual unicast/broadcastservice flow level via correlated mapping with critical attributes(e.g., application layer—streams, duration, battery life, securitycontrols, signal processing layer—serving area geo-fencing, spectrumresources utilized for broadcast/unicast, RSSI, SNR, FEC rates in agiven serving area) and maintain a transient inventory of the mobilitypath for a device. By providing on-demand threshold-based triggers viamobile originated unicast data connections, the connected-car deviceplatform can be in a position to securely relay its behavioral-servicedelivery and quality patterns and tightly interwork with the networkfunctions to adapt its usability conditions to derive more optimaldownstream broadcast service quality.

FIG. 1 illustrates some example components of a typical wirelesscommunication system 100 (also referred to as wireless system 100,mobile system 100, mobile communications system 100). In exampleembodiments (also referred to as non-limiting embodiments), wirelesscommunications system 100 can comprise a mobile (also referred to ascellular) network 106, which can comprise one or more mobile networkstypically operated by communication service providers. The wirelesscommunication system 100 can also comprise one or more user equipment(UE) 102 _(1-N) (also referred to as UE 102). UE 102 _(1-N) cancommunicate with one another via one or more network node devices (alsoreferred to as network nodes) 104 _(1-N) (referred to as network node104 in the singular) of the mobile network 106. The dashed arrow linesfrom the network nodes 104 _(1-N) to the UE 102 _(1-N) representdownlink (DL) communications and the solid arrow lines from the UE 102_(1-N) to the network nodes 104 _(1-N) represent uplink (UL)communications.

UE 102 can comprise, for example, any type of device that cancommunicate with mobile network 106, as well as other networks (seebelow). The UE 102 can have one or more antenna panels having verticaland horizontal elements. Examples of a UE 102 comprise a target device,device to device (D2D) UE, machine type UE, or UE capable of machine tomachine (M2M) communications, personal digital assistant (PDA), tablet,mobile terminal, smart phone, laptop mounted equipment (LME), universalserial bus (USB) dongles enabled for mobile communications, a computerhaving mobile capabilities, a mobile device such as cellular phone, adual mode mobile handset, a laptop having laptop embedded equipment(LEE, such as a mobile broadband adapter), a tablet computer having amobile broadband adapter, a wearable device, a virtual reality (VR)device, a heads-up display (HUD) device, a machine-type communication(MTC) device, and the like. UE 102 can also comprise IOT devices thatcommunicate wirelessly. In example embodiments of the presentapplication, the UE 102 can be a C-V2X wireless device within a vehicle(e.g., C-V2X UE enabling C-V2X communications). Or, the vehicle itselfcan be said to be a C-V2X UE. In example embodiments of the presentapplication, as will be described below, a C-V2X UE can comprise asoftware application intelligence layer (e.g., an intelligent softwareagent based cross-layer monitoring mechanism) in place within theembedded device platforms (e.g., middleware) of the C-V2X UE.

Mobile network 106 can include various types of disparate networksimplementing various transmission protocols, including but not limitedto cellular networks, femto networks, picocell networks, microcellnetworks, internet protocol (IP) networks, Wi-Fi networks associatedwith the mobile network (e.g., a Wi-Fi “hotspot” implemented by a mobilehandset), and the like. For example, in at least one implementation,wireless communications system 100 can be or can include a large scalewireless communication network that spans various geographic areas, andcomprise various additional devices and components (e.g., additionalnetwork devices, additional UEs, network server devices, etc.).

Still referring to FIG. 1, mobile network 106 can employ variouscellular systems, technologies, and modulation schemes to facilitatewireless radio communications between devices (e.g., the UE 102 and thenetwork node 104). While example embodiments might be described for 5GNew Radio (NR) systems, the embodiments can be applicable to any radioaccess technology (RAT) or multi-RAT system where the UE operates usingmultiple carriers. For example, wireless communications system 100 canbe of any variety, and operate in accordance with standards, protocols(also referred to as schemes), and network architectures, including butnot limited to: global system for mobile communications (GSM), 3GSM, GSMEnhanced Data Rates for Global Evolution (GSM EDGE) radio access network(GERAN), Universal Mobile Telecommunications Service (UMTS), GeneralPacket Radio Service (GPRS), Evolution-Data Optimized (EV-DO), DigitalEnhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/TDMA),Integrated Digital Enhanced Network (iDEN), Long Term Evolution (LTE),LTE Frequency Division Duplexing (LTE FDD), LTE time division duplexing(LTE TDD), Time Division LTE (TD-LTE), LTE Advanced (LTE-A), TimeDivision LTE Advanced (TD-LTE-A), Advanced eXtended Global Platform(AXGP), High Speed Packet Access (HSPA), Code Division Multiple Access(CDMA), Wideband CDMA (WCMDA), CDMA2000, Time Division Multiple Access(TDMA), Frequency Division Multiple Access (FDMA), Multi-carrier CodeDivision Multiple Access (MC-CDMA), Single-carrier Code DivisionMultiple Access (SC-CDMA), Single-carrier FDMA (SC-FDMA), OrthogonalFrequency Division Multiplexing (OFDM), Discrete Fourier TransformSpread OFDM (DFT-spread OFDM), Single Carrier FDMA (SC-FDMA), FilterBank Based Multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZTDFT-s-OFDM), Unique Word OFDM (UW-OFDM), Unique Word DFT-spread OFDM (UWDFT-Spread-OFDM), Cyclic Prefix OFDM (CP-OFDM), resource-block-filteredOFDM, Generalized Frequency Division Multiplexing (GFDM), Fixed-mobileConvergence (FMC), Universal Fixed-mobile Convergence (UFMC), MultiRadio Bearers (RAB), Wi-Fi, Worldwide Interoperability for MicrowaveAccess (WiMax), and the like.

Still referring to FIG. 1, in example embodiments, UE 102 can becommunicatively coupled (or in other words, connected) to a network node104 of the mobile network 106. Network node 104 can have a cabinet andother protected enclosures, an antenna mast, and multiple antennas forperforming various transmission operations (e.g., MIMO operations). Eachnetwork node 104 can serve several cells, also called sectors, dependingon the configuration and type of antenna. Network node 104 can compriseNodeB devices, base station (BS) devices, mobile stations, access point(AP) devices, and radio access network (RAN) devices. Network node 104can also include multi-standard radio (MSR) radio node devices,including but not limited to: an MSR BS, an eNode B device (e.g.,evolved NodeB), a network controller, a radio network controller (RNC),a base station controller (BSC), a relay device, a base transceiverstation (BTS), an access point, a transmission point (TP), atransmission/receive point (TRP), a transmission node, a remote radiounit (RRU), a remote radio head (RRH), nodes in distributed antennasystem (DAS), and the like. In 5G terminology, the network node isreferred to by some as a gNodeB (gNB) device, which provides NR userplane and control plane protocol terminations towards the UE, andconnects to the 5G core.

Referring now to FIG. 2, example embodiments of a mobile network of thepresent application can employ an architecture in which a user plane andcontrol plane are separate, wherein complex control plane functions areabstracted from forwarding elements, simplifying user plane operationsby relocating control logic to physical or virtual servers. Each planecarries a different type of traffic and can be implemented as overlaynetworks that runs independently on top of one another, althoughsupported by its infrastructure. The user plane (sometimes known as thedata plane, forwarding plane, carrier plane, or bearer plane) carriesthe network user traffic, and the control plane carries signalingtraffic. Typical control-plane functionality includes capabilities suchas the maintenance of location information, policy negotiation andsession authentication. In example embodiments, the planes can beimplemented in the firmware of routers and switches. As shown in FIG. 2,a mobile network (e.g., mobile network 106) with a centralized corenetwork (CN) can be decentralized, resulting in a distributed CN, whichacts as a controller in a mobile communication network, and performsunderlying tasks required for providing mobile communication services(e.g., user authentication, data transmission, etc.). To abstract thenetwork resources from the underlying physical hardware, the controlplane and user plane are separated, abstracting the network resourcesfrom the underlying physical hardware. This separation allows user-planefunctionality to move to the network edge, and management functionalityto remain at the core.

For example, as shown in FIG. 2, a gateway (GW) 205 in a centralized CNcan, in a distributed CN, be separated into a GW-CP 210 for the controlplane and GW-UP 215 for the user plane, wherein the user planefunctionality is closer to the network edge. In this distributed CN, thephysical core can be virtually separated and relocated in the networkinto multiple virtual core networks using virtualization technology.This software-defined networking (SDN) approach, can be complimentary toa network functions virtualization (NFV) approach, in which a virtualnetwork function (VNF) is responsible for handling specific networkfunctions (NFs) that run on one or more virtual machines (VMs) on top ofthe hardware networking infrastructure (e.g., routers, switches, etc.).Individual VNFs can be connected or combined to offer a particularnetwork communication service. Both SDN and VNF can facilitate theimplementation of network slicing (described further below). FIG. 7 andFIG. 8 below describe some more components that can be separated intocontrol and user planes.

Network services can be handled by decentralized virtual networkfunctions, called network slices, that are instantiated either for aspecific, dedicated service, or group of services, utilized bysubscribers or large enterprises. These slices are made to performspecific tasks depending on the location, quality of service (QoS) andcapacity of a given service. Thus, instead of having one network thatserves all devices on the network and performs all services, a singlephysical network can be sliced into multiple virtual networks that candraw from both CN and radio access network (RAN) resources to provide aspecific service. In this manner, network slices can be specificallyconfigured to support a multitude of use cases and new services. Eachuse case involves performance requirements that vary enormously. Asshown in FIG. 3, the bandwidth and latency related to each service canvary. IOT sensors and meters 305 might require service that is lowbandwidth and medium latency. Smartphones 310 might require highbandwidth and medium latency. Autonomous vehicles 315 relying on V2Xmight require low latency but not necessarily a high bandwidth for everycommunication application. Virtual reality video streaming 320 thatsupports video games and live sporting events might require a very highbandwidth, but low latency. As such, different use cases place differentrequirements on the network in terms of functionality. Each specificservice requires different resources, receiving a specific set ofoptimized resources and network topology that covers certain servicelevel agreement specified factors for delivering the service, includingsuch factors as such as connectivity, speed, latency and capacity. Forexample, for autonomous vehicle services 320, Ford, Lyft, or Chevy mighteach have a different service level agreement with a network provider tosupport their autonomous vehicle communication services.

Referring now to FIG. 4, a service orchestration manager 405 caninstantiate network slices 410 _(1-N) of the network comprisingcombinations of vNFs (virtual network functions (NFs)) on defaulthardware (HW) in order to reduce the network complexity, and providecapital savings on proprietary HW and software. Each network slice canbe instantiated, depending on, for example, the location (such asdedicated slice close to a large customer enterprise) or quality ofservice (e.g., high QoS slice for a premium service). These slices arepart of cloud network running on a default hardware with givenlimitations such as number of dedicated processors and memory, etc. Asshown in FIG. 4, with network slicing, each of these services can bedelivered over the same common physical network on multiple virtualnetwork slices to optimize use of the physical network. A slice #1 410 ₁can be instantiated to support IOT meters and sensors 305. A slice #2410 ₂ can serve smartphones. A slice #3 410 ₃ can serve autonomousvehicles 315. A slice #4 410 ₄ can support virtual reality videostreaming 320. N number of slices in the network (e.g., slice # N 410_(N)) can be instantiated to support other services. Each network slicecan comprise an independent set of logical, network functions NFs 415_(1-N) (also referred to herein as tasks) that support the requirementsof particular services (e.g., the term “logical” can refer to software),with some NFs that can be shared across multiple slices (e.g., NF1 415 ₁is common across the slices), while other NFs are tailored to aparticular network slice. An NF can comprise network nodes functionality(e.g. session management, mobility management, switching, routingfunctions) which has defined functional behavior and interfaces. Thus,NFs can be implemented as a network node (e.g., network node 104) on adedicated hardware or as virtualized software functions. The serviceorchestration manager device 405 can perform selection functions thatpair the resources and network topology (e.g., RAN and fixed access,terminal, transport, and CN resources) needed for the specific serviceand traffic that uses the slice. In this way, functions such as speed,capacity, connectivity and coverage can be allocated to meet thespecific demands of each use case. Not only can a network slice bespecifically instantiated for certain services, it can be reused.

In a typical C-V2X delivery network, as shown in FIG. 5, a C-V2Xreference architecture can use eMBMS broadcast core network functionsin, for example, an LTE mobility network, to deliver file downloads anddeliver live streaming from the content source (C-V2X application server505) to a large number of C-V2X UEs targeted in specific regions (e.g.,UEs 102 _(1-N), wherein a UE 102 can be enabled to communicate accordingto C-V2X standards, shown in the singular in FIG. 5 as C-V2X UE 505)C-V2X UE 505 can be a device in, or embedded in, for example a vehicle.A vehicle enabled with C-V2X communications can also be considered as aC-V2X UE. A variety of C-V2X UE device platforms could be used thatsupport the appropriate eMBMS chipset/modem and application clientcapabilities. These could be embedded in the automotive vehicle withintheir traffic control unit. While simple clients with standard modem andapplication functions can deliver the eMBMS user services, they areoften faced with challenges due to the dynamics of the radio conditions.

In this typical architecture as shown in FIG. 5 (e.g., a mobile network106 implementing, for example, an LTE network), the C-V2X applicationserver 510 triggers the broadcast (e.g., files, video streaming packets)to the head-end broadcast multicast service center (BMSC 515). Locatedat the core of the network, the BMSC manages the interface with contentproviders, including managing billing and the content to be transmittedover the mobile network. The BMSC initiates LTE broadcast sessionestablishment with the multimedia broadcast multicast service gateway(MBMS-GW 520), which in turn interacts with a management mobility entity(MME) and eNodeB 530 to complete the process. As mentioned above, anetwork node 104 in LTE terminology can be referred to as an eNodeB 530.Control plane eMBMS signaling can be initially established in themobility core network via multiple signaling interfaces between thevarious network functions: C-V2X Application Server-BMSC via theMB2-C/xMB-C interface, BMSC-MBMS GW via the SGmb interface, MBMS GW-MMEvia the Sm interface, MME-eNB via M3 interface and eNB-UE via the Uuinterface. The radio access network (RAN) eNodeB 530 joins the MBMS GWupon session completion to start receiving the user data from the MBMSGW via the M1 interface. User data from C-V2X-Application Server istransferred to BMSC via MB2-U/xMB-U interface, and from the BMSC to MBMSGW via the SGi-mb interface. With multiple interfaces involved in thecontrol plane setup, the session establishment times could be longerdepending on the geographical location of the various core networkfunctions.

Additionally, the RAN can be provisioned with the band specificinformation for associated LTE-B data transfers—statically ordynamically based on external triggers from spectrum management systems,based on their availability and utilization in a given geographic area.UE devices (C-V2X UE 505) can tune into the broadcast as long as theysupport the client and are in the multi-frequency single-frequencynetwork (MBSFN) spectral radio coverage area.

Moving on to FIG. 6, the network functions and components supportingboth unicast and broadcast services are shown. Unicast data connectionestablishments follow the standard packet data network (PDN) connectionsetup process with bearer establishments. Contrary to unicastconnections that require a specific access point name (APN), broadcastservices do not require any APN subscription within the home subscriberserver (HSS) systems. The broadcast services are triggered by the C-V2Xapplication server (e.g., C-V2X application server 510) within thecontent delivery network at operator defined intervals and for a givenduration in a given location.

Still referring to FIG. 6, core network functions such asBMSC/MBMS-GW/MME/SGW/PGW and AS can be virtualized and can be hosted ina cloud data center. In FIG. 6, the path of unicast data moves through apacket data network gateway (PGW) and a serving gateway (SGW). These twocomponents performing the PGW and SGW functions are shown as PGW 605 andSGW 610 in FIG. 6. These functions can be centralized or distributedbased on operator's deployment model for mobility services delivery. Asubset of these functions can be co-located closer to the RAN clusterswhere appropriate to reduce the latency aspects of targeted multicastuser plane data transfers in a given broadcast serving area. RAN nodescan be LTE-broadcast capable in concentrated areas serving both unicastand multicast data transfers (e.g., dashed lines in FIG. 6) acrossmultiple spectrum allocations and availability in a given geographicarea. Spectrum analysis and monitoring can ensure proper utilization ofbroadcast and unicast resources in real time to provide maximum returnon investment (ROI) to operators.

While the broadcast core network components can be hosted along with theunicast core network functions, such deployments may not necessarily beoptimal for flexible service offerings. All core functions could bephysical or virtualized in data centers and could be deployed in acentralized or distributed configurations to meet specific operatorneeds. A subset of the core network functions, such as broadcast nodes,could be localized to meet the stringent service quality needs.

Due to the heavy control plane and user data forwarding interactionsrequired to support a mix of unicast and broadcast services, the corenetwork components with their traditional integrated control and userplane functions may be limited with respect to their capacity andscalability while supporting geo-redundancy. To address the scale,multiple functions need to be replicated in several data centerlocations which could become very expensive. Even with NFV/SDNtransformation, such virtual functions may need to be instantiated atseveral data centers and may still be limited by the underlying networkinfrastructure reliability when supporting a mix of complex protocolsand their associated packet handling functions at the transport layer.Additionally, disjoint unicast and broadcast configurations operating ina standalone manner is not optimal and could result in a networkutilization imbalance as well as being prohibitively expensive due tospectrum allocations in certain deployment situations.

The present application facilitates the mitigation of the abovesituation by separating control and user plane functions for broadcastcore network functions as shown in FIG. 7. While 3GPP Re1.14 standardshave recently completed the control and user plane separation (CUPS)feature in the EPC core network for unicast data services, no such modeland/or feature capability exists for broadcast (e.g., multicast) corenetwork functions. Referring to FIG. 7, in example embodiments inaccordance with the present application, there two signaling interfacesSxe and Sxd, between the MBMS GW Control and User Plane functions aswell as between the BMSC Control and User plane functions areestablished. As shown in FIG. 7, the MBMS-GW 520 and the BMSC 515 can beseparated based on control plane and user plane functionality. Thus, theBMSC 515 can be separated into a BMSC-Control Plane (e.g., BMSC-CP 705)and BMSC-User Plane (e.g., BMSC-UP 710), and the MBMS-GW 520 can beseparated into a MBMS-GW-Control Plane (MBMS-GW-CP 715) and MBMS-GW-UserPlane (MBMS-GW-UP 720). The separation also results in an interfacebetween the BMSC-CP and BMSC-UP (Sxe 725), and an interface between theMBMS-GW-CP and MBMS-GW-UP (Sxd 730) Such separation offers flexibilityfor operators to deploy broadcast control and user plane functions in acentralized and/or distributed configuration and scale independentlybased on as needed basis in targeted locations. Localizing user planebroadcast functions closer to the RAN can significantly benefitdeployments and can simplify the mobility network infrastructure costeconomics. Several advantages can result for mobile operators as well ascontent providers by being able to competitively position themselves fordisruptive localized and targeted broadcast services. Such networkconfigurations can drive reduced backhaul requirements, benefiting livestreaming service flows that are extremely sensitive to latency, delay,radio link errors and channel switching times. By monitoring the controland user plane functions in conjunction with the intelligence receptionreports received from the end points, viewing experiences could befurther enhanced locally that could in turn drive services adoption.

FIG. 8 shows example embodiments in accordance with the presentapplication of an integrated evolved control and user plane separation(eCUPS) for more efficient and dynamic unicast/multicast flow transfer,wherein, the PGW (e.g., PGW 605) and SGW (e.g., SGW 610) are alsoseparated into control plane and user plane. Thus, as shown in FIG. 8,the PGW can be separated into a PGW-User Plane (PGW-UP 805) and aPGW-Control Plane (e.g., PGW-CP 810), and the SGW can be separated intoan SGW-User Plane (e.g., SGW-UP 815) and SGW-Control Plane (e.g., SGW-CP820). With integrated control and user plane functions separationsupporting both unicast and broadcast services as shown in FIG. 8,operators have even better flexibility in terms of network deploymentand operations benefiting service dynamics in targeted locations. Suchan architecture also facilitates independent scaling between control anduser plane functions for simultaneous unicast and multicast/broadcastsession/connection establishments as well as associated user datatransfers while not impacting legacy functionality of the existing nodesundergoing the functional split.

As mentioned above with respect to FIG. 4, network slices can bespecifically configured to support a multitude of use cases and newservices. Mobile operators could leverage NFV/SDN principles to slicethe control/user plane network functions for unicast/broadcast andorchestrate such functions in the most desirable high-densityenvironments (concerts, trade shows, school/college game events etc.)where the impact is extremely high with respect to delivering superiorservice quality. In FIG. 9, where the users with specific device typesare distributed across multiple broadcast serving areas within a givenMBSFN region, localized core user plane deployments can yield muchbetter performance results during mobility. Based on a closed loopmonitoring within the devices (e.g., C-V2X UEs) in targeted broadcastareas and reports of service quality, user plane broadcast functions canbe scaled locally and independently of the control plane broadcastfunctions to enhance the end user experience. Based on the eMBMS servicequality reception reports received from connected cars and processed bythe C-V2X application server, it can immediately trigger enhancedapplication layer FEC (AL-FEC) rates to localized BMSC-CP, which in turncan send updates in targeted broadcast serving areas where the endpoints can selectively use that information based on dynamics of theirradio conditions.

As an example, as shown in FIG. 9, eMBMS communications can involveseveral layers, for example, the application/service layer 905, themobility core network layer 910, the mobility transport network layer915, and the radio access network layer 920 (which the network nodes 104are part of). At the application/service layer 905, a C-V2X applicationserver can transmit, for example, video data, destined for C-V2X UEs indifferent service areas. Connected cars during mobility can crossbroadcast serving areas (service area 1 925, service area 2 930, servicearea 3 935, service area N 940) as shown in FIG. 9, and may operate inmulti-mode based on their embedded device platform capabilities. Theymay be able to switch from one device category to another (ex: CAT 4 toCAT 6 or CAT 19 or CAT 1) based on the intelligence synthesized by themiddleware that works across the modem-application layers at the serviceflow level, as shown in FIG. 10 and FIG. 11. In each serving area, dueto transmission conditions, one FEC code might be more suitable thananother FEC code. Example embodiments of the present application allowfor the selection of different FEC codes for different service areas,based on feedback provided, triggered by an analysis of the transmissionconditions experienced by the C-V2X UE.

As shown in FIG. 10, the application/service layer 905 (e.g., anapplication server device, such as C-V2X application server 510)triggers the broadcast content to be delivered to the end user (e.g.,C-V2X UE 505 ₁, C-V2X UE 505 ₂). The LTE-broadcast headend receives thedata feed to be broadcasted to device/s in a given geographic area(MBSFN). Core, Transport and Access network functions are invoked tosupport the LTE broadcast session establishment. The eNB can beLTE-broadcast capable and operate with multiple licensed-unlicensedfrequency bands/carriers. All supported bands might not be used forbroadcast data transfer based on provisioning and service requirements.The eNB has the intelligence to schedule downlink (DL) user datatransfers in a given band (By) upon joining the multicast group with theMBMS GW in the core network using the M1 interface. The C-V2X UE istuned to both bands Bx and By being transmitted by eNB. Bx can be usedfor DL/UL notifications/triggers from the eNB/UE for an impendingbroadcast data transfer/related communication. Actual user data transferis received in band By only to meet the service criteria.

Referring now to FIG. 11, example embodiments of a C-V2X UE (e.g., C-V2XUE 505) can provide feedback to the mobile core, leading to anadjustment to application layer forward error correction (AL-FEC), aswill be described further below. Given the various degrees of freedomavailable in the network with spectrum allocation, active carriers,resource utilizations, aggregate capacity, services priority, FEC rateallocation and adaptation per flow in use, radio channel conditions, andservice quality per active flow, the C-V2X UE 505 executing middlewarein the C-V2X UE 505 can trigger generation of reception reports ornotifications based on policy driven rules and/or threshold alerts(e.g., if a quality of service becomes low, or an SNR becomes high, orif a certain number of errors in a time period has been reached, etc.).The C-V2X UE can engage in cross-layer analysis (e.g., examine thephysical layer, service layer, etc.) so as to correlate differentattributes within the layers and make a determination as to whether theFEC code that is currently being used is optimal, or whether anadjustment needs to be made (e.g., use another FEC rate, or another FECcode, that would be more optimal). The reports and alerts (e.g.,feedback) can be transmitted via a unicast uplink (UL) channel to thelocalized broadcast core network head-end. Such feedback can beextremely conducive for the network to be intelligent, and drive controlof the application layer attributes, including application layer forwarderror correction (AL-FEC) in the devices in coordination with the modemlayer FEC on a per-flow basis within a given serving area. Additionally,a broadcast resource mapping function component 1105, can track all theresource utilizations across the layers, which gives the C-V2X UE (e.g.,the software agent within the device) a way to correlate all thedifferent cross-layer attributes, which can allow it to provide anadjustment to the output FEC.

In example embodiments in accordance with the present application, aC-V2X UE (e.g., C-V2X UE 505) comprising a processor and a memory thatstores executable instructions (e.g., middleware in example embodiments)that, when executed by the processor, enable the C-V2X UE 505 to monitorthe conditions of transmissions to the C-V2X UE, and based on ananalysis of parameters associated with the transmissions, providefeedback regarding which forward error correction code to use fordecoding received transmissions. The feedback can be sent through thenetwork core to an application layer server device (e.g., C-V2Xapplication server 510) that broadcasts content to C-V2X UEs. In exampleembodiments, the C-V2X UE can receive a transmission (e.g., livestreaming content) from a network device (e.g., network node) of amobile network via a communication channel. The C-V2X UE can decode thistransmission using a forward error correction code (e.g., first forwarderror correction code). The C-V2X UE can determine one or moreattributes of the transmission to determine a condition of thecommunications channel. The attribute might relate to a physicalcondition of the channel. For example, the C-V2X UE can determine asignal to noise ratio (SNR) relate to the transmissions. The attributemight relate to a quality of service (e.g., a measured bandwidth).Another attribute might be the number of times there were errors in thetransmissions (e.g., based a per flow basis, or based on a periodicbasis). Each time that the number of bits in a transmission do not matchup with the bits of a FEC code can be counted. If the SNR is too high,or the bandwidth is lower than an acceptable quality of service, or ifthere are too many errors, the condition of the communications channelcan be determined to be poor, or not optimal. The C-V2X UE executingthis middleware software can engage in cross-layer analysis andcorrelation, looking at all the attributes of these layers together todetermine whether an adjustment in the FEC rate (e.g., select adifferent FEC code, for example) can be made that results in moreoptimum transmissions (e.g., reduction in errors in transmissions).

As such, based on the condition of the communication channel, the userequipment can facilitate transmitting feedback to the network device(e.g., network node 104), wherein the feedback is forwarded by thenetwork device to an application server device that selects a secondforward error correction code based on the feedback. As an example, ifthe feedback indicates that the channel conditions are poor, theapplication server device can select a second forward error correctioncode (e.g., one in which each FEC code word is longer) to be used by theC-UE device to decode subsequent transmissions. The application servercan, in example embodiments, send the FEC code to be used by the C-V2XUE. In example embodiments, the C-V2X UE acknowledges the receipt of theFEC code by sending an acknowledgement to the application server. TheC-V2X application server can then begin sending transmissions encodedwith the newly selected FEC, and the C-V2X UE can decode thetransmissions with the newly selected FEC. The new FEC correction codecan not only be transmitted to the C-V2X UE, but can be broadcast toother C-V2X UE devices in the same service area, as those devices mightbe experiencing similar transmission conditions.

In other example embodiments, if the C-V2X UE already has stored in itsmemory the FEC codes, after evaluating the feedback and selecting a FECcode, the application server can send a message to the C-V2X UEindicating which FEC code the C-V2X UE should use for futuretransmissions (at least until monitored channel conditions warrantanother change in the FEC being used). The C-V2X UE acknowledges thereceipt of the indication message by sending an acknowledgement to theapplication server. The application server can then begin sendingtransmissions encoded with the newly selected FEC, and the C-V2X UE candecode the transmissions with the newly selected FEC.

In other example embodiments, it is the C-V2X UE that select the FEC tobe used, and either sends the selected FEC code to the applicationserver, or sends a message indicating to the application server whichFEC code the application server should use for encoding subsequenttransmissions from the application server to the C-V2X UE. Theapplication server can send an acknowledgement indicating that it hasreceived the message indicating which FEC code it should use. Once theacknowledgement has been sent, the application server can begin sendingtransmissions encoded with the FEC code selected by the C-V2X UE.

Now referring to FIG. 12, in example embodiments, the middlewarecorrelation engine embedded in the device platform facilitates the C-V2XUE 505's monitoring capability on a per-flow level via cross-layerinteractions, and then, based on policy driven threshold alerts (e.g.,if an SNR reaches a threshold, or a bandwidth dips to a threshold,etc.), enables the C-V2X UE to provide of feedback to the network via adedicated PDN connection using a specific APN. The PGW then notifies thetargeted application server (C-V2X application server 510) destined toreceive such feedback (e.g., a report, dashboard).

Once the C-V2X application server receives the feedback (e.g., report,dashboard), it can take proactive action to broadcast the FEC rateadaptations across the serving areas via the localized broadcast corenetwork. By providing an on-demand threshold-based triggers per flow viamobile originated unicast data connections to the content deliverynetwork head-end, the connected-car device platform is able to securelyrelay its behavioral-service flow delivery and quality patterns andtightly interwork with the mobility network functions to adapt itsusability conditions to derive a more optimal downstream quality ofservice.
